Distal-less homeobox 2 (Dlx2) is a member of the homeodomain family of transcription factors and is important for the development of cranial neural crest cells (CNCCs)‑derived craniofacial tissues. Previous studies revealed that Dlx2 was expressed in the cementum and a targeted null mutation disrupted tooth development in mice. However, whether Dlx2 overexpression may impair in vivo tooth morph...

The defects of the alveolar ridge can result from various causes, most common being the collapse of alveolar bone during extraction. Localized defects of alveolar crest impair prosthetic rehabilitation due to poor emergence profile of function. Several alternatives have been proposed to restore the damaged ridge by hard and soft tissue augmentation. Various soft tissue ridge augmentation techni...

Major research carried out in modern dentistry and maxillofacial surgery is commonly focused on long-term stable results for implant rehabilitation of jaw defects deformities patients with bone soft tissue losses at the site planned implantation. Various osteoplastic materials, donor or patient’s own bone, tissue-engineering cellular products are common clinical medicine, since guided regenerat...

The aim of this study was to evaluate in situ changes in the alveolar crest bone height around immediate implant-supported crowns in comparison to tooth-supported crowns (control) with the cervical margins located at the bone crest level, without occlusal load. In Group I, after extraction of 12 mandibular premolars from 4 adult dogs, implants from Branemark System (MK III TiU RP 4.0 x 11.5 mm)...

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. Surgical resection of the ameloblastoma is well-documented and an accepted treatment modality. Vertical distraction of the alveolar process is an efficient method for augmentation. This method of providing additional bone and soft tissue for implant placement is becoming more common. This clinical report describes the use of dis...

Objective This study aimed to explore the usefulness of adjunctive buccal and palatal corticotomy for adult maxillary expansion in an animal model using cone-beam computed tomography (CBCT). Methods Twelve adult sheep were randomly divided into two groups (each n = 6): a control group, where no treatment was administered, and a treatment group, where buccal and palatal corticotomy-assisted ma...

OBJECTIVE To evaluate nasal morphology, symmetry, and nostril shape in patients with unilateral cleft lip and palate following mixed-dentition alveolar bone grafting. DESIGN Prospective stereophotogrammetric study. SETTING Hospital-based. PATIENTS Thirty-nine patients with a history of repaired unilateral cleft lip and palate who received an iliac crest alveolar bone graft were recruited ...

Narrow alveolar ridges remain a serious challenge for the successful placement of endosseous implants. This article reports a technique for widening the atrophic ridge by splitting the alveolar bone longitudinally and filling the bone gap with collagenised pig bone, treatment of ridges as thin as 2.5mm at the alveolar crest and simultaneous placement of dental implants. Treatment of a 22-year-o...

BACKGROUND The use of osteotome for vertical bone augmentation and localized sinus elevation with minimal surgical trauma represents a suitable procedure to increase the vertical dimension of available bone for implant placement. PURPOSE The aim of this study was to report clinical and radiographic results of localized management of sinus floor (LMSF) in fresh molar sockets at 13-year follow-...

INTRODUCTION Alveolar bone grafting is a vital part of the rehabilitation of cleft patients. The factors that have been most frequently associated with the success of the graft are the age at grafting and the pre-grafting orthodontic treatment. OBJECTIVES 1) Describe the cases of alveolar bone grafts performed at the Maxilofacial Unit of Hospital Sant Joan de Déu, Barcelona (HSJD); and 2) Ana...
